This is my game submit in javafx challenge. This is a car race in real track. You can set start address and end address and run in multiplayer in real routing generated track (you can see your home street). In this game there is a phyisic library, RMI, and DigLayout library all open source. There are some track generating algoritmics. I mashup data from free api multimap.com for routing point and yahoo api for geocoding.
